3) If an object has a net negative charge of 4.0 Coulombs, the object possesses
1) 6.3 x 1018 more electrons than protons
2) 2.5 x 1019 more electrons than protons
3) 6.3 * 1018 more protons than electrons
4) 2.5 * 1019 more protons than electrons

Respuesta :

Answer:

2.5*10^19 more electrons than protons

Explanation:

1 coulomb equals 6.25*10^18 elementary charges. 4 coulombs equals 2.5*10^19 elementary charges. But because the net charge is negative, it can be inferred that there are more electrons than protons. How much more? The net charge is -4 coulombs. Therefore, there are 2.5*10^19 more electrons than protons.

The number of excess electrons or protons is required to be identified in the given case.

The correct option is 2) [tex]2.5\times 10^{19}[/tex] more electrons than protons.

The object has a charge of [tex]-4\ \text{C}[/tex]

[tex]1\ \text{C}=\dfrac{1}{1.602\times 10^{-19}} \text{Charges}[/tex]

[tex]4\ \text{C}=4\times \dfrac{1}{1.602\times 10^{-19}}=2.5\times 10^{19}\ \text{Charges}[/tex]

Since, it is negative in nature it has a surplus of electrons..

So, the correct option is 2) [tex]2.5\times 10^{19}[/tex] more electrons than protons.
